ALZ51B24TW

The ALZ51B24TW relay is a high-performance, cost-effective electromechanical device designed to switch or control electrical circuits. It is a type of power relay with a current of over 2 amps, designed to be used in high demand applications such as motor control, industrial automation, power supplies, power management, and motor starting systems.

It is a 5 pin DIN rail mountable device composed of a coil laminations in the form of a bobbin, an armature actuated by the coil, a movable contact, and a fixed contact. The ALZ51B24TW is composed of two SPDT (Single-Pole Double-Throw) contacts, which allows for switching or controlling two independent circuits.

Working Principle

The operation of the ALZ51B24TW relies on the electromagnetic principle. It works by passing a current through the coil, which in turn activates an armature and moves a contact. The armature is linked to the movable contact as the coil contracts when a current is passed through. When the circuit is opened, the coil expands and the armature returns, bringing the two contacts back together.

The ALZ51B24TW is designed for high continuous current switching, meeting UL 508 and EN 60947-4-1 requirements for short-circuit and high inrush current ratings. It also has a mechanical life expectancy of up to 30 million operations and an insulation resistance of up to 5000MΩ at 500VAC.

Application Field

Due to its high continuous current switching capability, the ALZ51B24TW relay is suitable for a wide range of applications, including motor control, industrial automation, power supplies, power management, and motor starting systems. It is also suitable for applications where the load needs to be switched or monitored, such as HVAC systems, agricultural machinery, emergency alarm systems, traffic controllers, industrial process controllers, and process monitoring systems.

The ALZ51B24TW is suitable for applications where safety is a priority. It features a zero voltage switch for high inrush current control, as well as a visual operation indication for confirmation. It also features protection against short circuits, overloads, and other contingencies.

The ALZ51B24TW is designed to offer reliable performance in the most demanding industrial applications. With a current rating of over 2 amps, it is an efficient and cost-effective solution for motor control, industrial automation, power management, and other demanding applications.
